This compact Denver ADU was constructed by Prenvalley Builders as an efficient, small-footprint backyard residence. Built on a helical pier foundation to reduce site impact and control costs, the project required thoughtful sequencing, precision framing, and careful coordination to maximize usable space. The result is a durable, well-built accessory dwelling unit designed to perform efficiently within a tight urban lot.

This detached backyard ADU in Colorado Springs marked Prenvalley Builders’ first accessory dwelling unit project and the beginning of their ADU expertise. Designed as a compact cottage, the home features an efficient layout with a full kitchen, bathroom, bedroom, and in-unit laundry. The project established a strong foundation for Prenvalley’s refined approach to thoughtful, high-quality ADU construction.
